To calculate the concentration of a solution using acid–base titration data. In an acid–base titration, an acid (or base) of known concentration is added to a base (or acid) of unknown concentration until the number of moles of H+ and OH- are equal, a condition called the equivalence point. Since you know the number of moles of H+ (or OH- ) that you added, you can determine the number of moles of OH- (or H+) in the unknown solution. For...

A chemist needs to determine the concentration of a solution of nitric acid, HNO3. She puts 905 mL of the acid in a flask along with a few drops of indicator. She then slowly adds 0.600 M Ba(OH)2 to the flask until the solution turns pink, indicating the equivalence point of the titration. She notes that 205 mL of Ba(OH)2 was needed to reach the equivalence point. a) How many moles of Ba(OH)2 are present in 205 mL of 0.600...

A chemist needs to determine the concentration of a solution of nitric acid, HNO3. She puts 875 mLof the acid in a flask along with a few drops of indicator. She then slowly adds 0.200 MBa(OH)2 to the flask until the solution turns pink, indicating the equivalence point of the titration. She notes that 145 mL of Ba(OH)2 was needed to reach the equivalence point. Solution map In this titration, the concentration of base is known and can be used...
